SotU * Refired (originally, Re-Searchers of the Unknown) is a one-page old school inspired rpg, based on SotU. It adds races (elves, dwarves, and men), classes (fighters, thieves, and wizards) with different movement rates, helmets, additional weapons, and rules for spellcasting.

Version 3 has some changes in rules. Demihumans vision is tuned, hp increase is faster etc.
